CROSS-REFERENCE TO RELATED APPLICATIONS

Pursuant to 35 U.S.C. § 119(e), this application claims the benefit of U.S. Provisional Patent Application No. 62/400,062, filed on Sep. 26, 2016, 62/440,408, filed on Dec. 30, 2016, and 62/416,103, filed on Nov. 1, 2016, the contents of which are all hereby incorporated by reference herein in their entirety.

FIELD OF THE INVENTION

The present invention relates to mobile communication.

RELATED ART

3rd generation partnership project (3GPP) long term evolution (LTE) evolved from a universal mobile telecommunications system (UMTS) is introduced as the 3GPP release 8. The 3GPP LTE uses orthogonal frequency division multiple access (OFDMA) in a downlink, and uses single carrier-frequency division multiple access (SC-FDMA) in an uplink. The 3GPP LTE employs multiple input multiple output (MIMO) having up to four antennas. In recent years, there is an ongoing discussion on 3GPP LTE-advanced (LTE-A) evolved from the 3GPP LTE.

In LTE/LTE-A, a physical channel of LTE may be classified into a downlink channel, i.e., a PDSCH (Physical Downlink Shared Channel) and a PDCCH (Physical Downlink Control Channel), and an uplink channel, i.e., a PUSCH (Physical Uplink Shared Channel) and a PUCCH (Physical Uplink Control Channel).

A frequency which can be used for LTE/LTE-A, that is, a carrier is defined in 3GPP by considering radio wave situations of various countries.

Meanwhile, when a terminal configured with a carrier aggregation of two downlink (DL) carriers transmits an uplink signal, a harmonic is generated, thereby influencing a downlink band of the terminal itself.

SUMMARY OF THE INVENTION

Accordingly, an object of the present invention is to solve the above-mentioned problems.

To achieve the foregoing purposes, the disclosure of the present invention proposes a method for transmitting/receiving a signal in carrier aggregation. The method may comprise: transmitting an uplink signal by using two uplink carriers when three downlink carriers and two uplink carriers are configured to be aggregated. The three downlink carriers include three operating bands among evolved universal terrestrial radio access (E-UTRA) operating bands 1, 2, 3, 5, 12, 30 and 40 and the two uplink carrier includes two operating bands thereamong. The method may comprise: receiving a downlink signal through all of three downlink carriers. Here, a predetermined maximum sensitivity degradation (MSD) is applied to receiving reference sensitivity of the downlink signal, thereby successfully receiving the signal.

When the three downlink carriers include operating bands 1, 3 and 40 and when two uplink carriers include operating band 1 and 3, the MSD value may be 8.0 dB for the downlink carrier of the operating band 40.

When the three downlink carriers include operating band 1, 5 and 40 and when two uplink carriers include operating band 1 and 5, the MSD value may be 9.0 dB for the downlink carrier of the operating band 40.

When the three downlink carriers include operating band 2, 12 and 30 and when two uplink carriers include operating band 2 and 12, the MSD value may be 12.0 dB for the downlink carrier of the operating band 30.

To achieve the foregoing purposes, the disclosure of the present invention proposes a wireless device for transmitting/receiving a signal in carrier aggregation. The wireless device may comprise: a transmitter configured to transmit an uplink signal by using two uplink carriers when three downlink carriers and two uplink carriers are configured to be aggregated. The three downlink carriers include three operating bands among evolved universal terrestrial radio access (E-UTRA) operating bands 1, 2, 3, 5, 12, 30 and 40 and the two uplink carrier includes two operating bands thereamong. The wireless device may comprise: a receiver configured to receive a downlink signal through all of three downlink carriers. Here, a predetermined maximum sensitivity degradation (MSD) is applied to receiving reference sensitivity of the downlink signal, thereby successfully receiving the signal.

According to the disclosure of the present invention, the problem of the conventional technology described above may be solved.

This is just an example, and the present invention may be applied to various wireless communication systems. Hereinafter, LTE includes LTE and/or LTE-A.

The technical terms used herein are used to merely describe specific embodiments and should not be construed as limiting the present invention. Further, the technical terms used herein should be, unless defined otherwise, interpreted as having meanings generally understood by those skilled in the art but not too broadly or too narrowly. Further, the technical terms used herein, which are determined not to exactly represent the spirit of the invention, should be replaced by or understood by such technical terms as being able to be exactly understood by those skilled in the art. Further, the general terms used herein should be interpreted in the context as defined in the dictionary, but not in an excessively narrowed manner.

The expression of the singular number in the present invention includes the meaning of the plural number unless the meaning of the singular number is definitely different from that of the plural number in the context. In the following description, the term ‘include’ or ‘have’ may represent the existence of a feature, a number, a step, an operation, a component, a part or the combination thereof described in the present invention, and may not exclude the existence or addition of another feature, another number, another step, another operation, another component, another part or the combination thereof.

The terms ‘first’ and ‘second’ are only used to distinguish one component from another component. For example, a first component may be named as a second component without deviating from the scope of the present invention.

It will be understood that when an element or layer is referred to as being “connected to” or “coupled to” another element or layer, it can be directly connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present.

Hereinafter, exemplary embodiments of the present invention will be described in greater detail with reference to the accompanying drawings. In describing the present invention, for ease of understanding, the same reference numerals are used to denote the same components throughout the drawings, and repetitive description on the same components will be omitted. Detailed description on well-known arts which are determined to make the gist of the invention unclear will be omitted. The accompanying drawings are provided to merely make the spirit of the invention readily understood, but not should be intended to be limiting of the invention. It should be understood that the spirit of the invention may be expanded to its modifications, replacements or equivalents in addition to what is shown in the drawings.

As used herein, ‘base station’ generally refers to a fixed station that communicates with a wireless device and may be denoted by other terms such as eNB (evolved-NodeB), BTS (base transceiver system), or access point.

As used herein, ‘user equipment (UE)’ may be stationary or mobile, and may be denoted by other terms such as device, wireless device, terminal, MS (mobile station), UT (user terminal), SS (subscriber station), MT (mobile terminal) and etc.

FIG. 1 Illustrates a Wireless Communication System.

As seen with reference to FIG. 1, the wireless communication system includes at least one base station (BS) 20. Each base station 20 provides a communication service to specific geographical areas (generally, referred to as cells) 20 a, 20 b, and 20 c. The cell can be further divided into a plurality of areas (sectors).

The UE generally belongs to one cell and the cell to which the UE belong is referred to as a serving cell. A base station that provides the communication service to the serving cell is referred to as a serving BS. Since the wireless communication system is a cellular system, another cell that neighbors to the serving cell is present. Another cell which neighbors to the serving cell is referred to a neighbor cell. A base station that provides the communication service to the neighbor cell is referred to as a neighbor BS. The serving cell and the neighbor cell are relatively decided based on the UE.

Hereinafter, a downlink means communication from the base station 20 to the UE1 10 and an uplink means communication from the UE 10 to the base station 20. In the downlink, a transmitter may be a part of the base station 20 and a receiver may be a part of the UE 10. In the uplink, the transmitter may be a part of the UE 10 and the receiver may be a part of the base station 20.

Meanwhile, the wireless communication system may be generally divided into a frequency division duplex (FDD) type and a time division duplex (TDD) type. According to the FDD type, uplink transmission and downlink transmission are achieved while occupying different frequency bands. According to the TDD type, the uplink transmission and the downlink transmission are achieved at different time while occupying the same frequency band. A channel response of the TDD type is substantially reciprocal. This means that a downlink channel response and an uplink channel response are approximately the same as each other in a given frequency area. Accordingly, in the TDD based wireless communication system, the downlink channel response may be acquired from the uplink channel response. In the TDD type, since an entire frequency band is time-divided in the uplink transmission and the downlink transmission, the downlink transmission by the base station and the uplink transmission by the terminal may not be performed simultaneously. In the TDD system in which the uplink transmission and the downlink transmission are divided by the unit of a sub-frame, the uplink transmission and the downlink transmission are performed in different sub-frames.

Hereinafter, the LTE system will be described in detail.

FIG. 2 Shows a Downlink Radio Frame Structure According to FDD of 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE).

The radio frame includes 10 sub-frames indexed 0 to 9. One sub-frame includes two consecutive slots. Accordingly, the radio frame includes 20 slots. The time taken for one sub-frame to be transmitted is denoted TTI (transmission time interval). For example, the length of one sub-frame may be 1 ms, and the length of one slot may be 0.5 ms.

The structure of the radio frame is for exemplary purposes only, and thus the number of sub-frames included in the radio frame or the number of slots included in the sub-frame may change variously.

Meanwhile, one slot may include a plurality of orthogonal frequency division multiplexing (OFDM) symbols. The number of OFDM symbols included in one slot may vary depending on a cyclic prefix (CP). One slot includes 7 OFDM symbols in case of a normal CP, and one slot includes 6 OFDM symbols in case of an extended CP. Herein, since the 3GPP LTE uses orthogonal frequency division multiple access (OFDMA) in a downlink (DL), the OFDM symbol is only for expressing one symbol period in a time domain, and there is no limitation in a multiple access scheme or terminologies. For example, the OFDM symbol may also be referred to as another terminology such as a single carrier frequency division multiple access (SC-FDMA) symbol, a symbol period, etc.

FIG. 3 Illustrates the Architecture of a Downlink Radio Frame According to TDD in 3GPP LTE.

Sub-frames having index #1 and index #6 are denoted special sub-frames, and include a DwPTS (Downlink Pilot Time Slot: DwPTS), a GP (Guard Period) and an UpPTS (Uplink Pilot Time Slot). The DwPTS is used for initial cell search, synchronization, or channel estimation in a terminal. The UpPTS is used for channel estimation in the base station and for establishing uplink transmission sync of the terminal. The GP is a period for removing interference that arises on uplink due to a multi-path delay of a downlink signal between uplink and downlink.

In TDD, a DL (downlink) sub-frame and a UL (Uplink) co-exist in one radio frame. Table 1 shows an example of configuration of a radio frame.

TABLE 1 Switch- UL-DL point Subframe index configuration periodicity 0 1 2 3 4 5 6 7 8 9 0 5 ms D S U U U D S U U U 1 5 ms D S U U D D S U U D 2 5 ms D S U D D D S U D D 3 10 ms  D S U U U D D D D D 4 10 ms  D S U U D D D D D D 5 10 ms  D S U D D D D D D D 6 5 ms D S U U U D S U U D

‘D’ denotes a DL sub-frame, ‘U’ a UL sub-frame, and ‘S’ a special sub-frame. When receiving a UL-DL configuration from the base station, the terminal may be aware of whether a sub-frame is a DL sub-frame or a UL sub-frame according to the configuration of the radio frame.

FIG. 4 Illustrates an Example Resource Grid for One Uplink or Downlink Slot in 3GPP LTE.

Referring to FIG. 4, the uplink slot includes a plurality of OFDM (orthogonal frequency division multiplexing) symbols in the time domain and NRB resource blocks (RBs) in the frequency domain. For example, in the LTE system, the number of resource blocks (RBs), i.e., NRB, may be one from 6 to 110.

The resource block is a unit of resource allocation and includes a plurality of sub-carriers in the frequency domain. For example, if one slot includes seven OFDM symbols in the time domain and the resource block includes 12 sub-carriers in the frequency domain, one resource block may include 7×12 resource elements (REs).

Meanwhile, the number of sub-carriers in one OFDM symbol may be one of 128, 256, 512, 1024, 1536, and 2048.

In 3GPP LTE, the resource grid for one uplink slot shown in FIG. 4 may also apply to the resource grid for the downlink slot.

FIG. 5 Illustrates the Architecture of a Downlink Sub-Frame.

In FIG. 5, assuming the normal CP, one slot includes seven OFDM symbols, by way of example.

The DL (downlink) sub-frame is split into a control region and a data region in the time domain. The control region includes up to first three OFDM symbols in the first slot of the sub-frame. However, the number of OFDM symbols included in the control region may be changed. A PDCCH (physical downlink control channel) and other control channels are assigned to the control region, and a PDSCH is assigned to the data region.

The physical channels in 3GPP LTE may be classified into data channels such as PDSCH (physical downlink shared channel) and PUSCH (physical uplink shared channel) and control channels such as PDCCH (physical downlink control channel), PCFICH (physical control format indicator channel), PHICH (physical hybrid-ARQ indicator channel) and PUCCH (physical uplink control channel).

FIG. 6 Illustrates the Architecture of an Uplink Sub-Frame in 3GPP LTE.

Referring to FIG. 6, the uplink sub-frame may be separated into a control region and a data region in the frequency domain. The control region is assigned a PUCCH (physical uplink control channel) for transmission of uplink control information. The data region is assigned a PUSCH (physical uplink shared channel) for transmission of data (in some cases, control information may also be transmitted).

The PUCCH for one terminal is assigned in resource block (RB) pair in the sub-frame. The resource blocks in the resource block pair take up different sub-carriers in each of the first and second slots. The frequency occupied by the resource blocks in the resource block pair assigned to the PUCCH is varied with respect to a slot boundary. This is referred to as the RB pair assigned to the PUCCH having been frequency-hopped at the slot boundary.

The terminal may obtain a frequency diversity gain by transmitting uplink control information through different sub-carriers over time. m is a location index that indicates a logical frequency domain location of a resource block pair assigned to the PUCCH in the sub-frame.

The uplink control information transmitted on the PUCCH includes an HARQ (hybrid automatic repeat request), an ACK (acknowledgement)/NACK (non-acknowledgement), a CQI (channel quality indicator) indicating a downlink channel state, and an SR (scheduling request) that is an uplink radio resource allocation request.

The PUSCH is mapped with a UL-SCH that is a transport channel. The uplink data transmitted on the PUSCH may be a transport block that is a data block for the UL-SCH transmitted for the TTI. The transport block may be user information. Or, the uplink data may be multiplexed data. The multiplexed data may be data obtained by multiplexing the transport block for the UL-SCH and control information. For example, the control information multiplexed with the data may include a CQI, a PMI (precoding matrix indicator), an HARQ, and an RI (rank indicator). Or, the uplink data may consist only of control information.

<Carrier Aggregation (CA>

Hereinafter, a carrier aggregation system will be described.

The carrier aggregation (CA) system means aggregating multiple component carriers (CCs). By the carrier aggregation, the existing meaning of the cell is changed. According to the carrier aggregation, the cell may mean a combination of a downlink component carrier and an uplink component carrier or a single downlink component carrier.

Further, in the carrier aggregation, the cell may be divided into a primary cell, secondary cell, and a serving cell. The primary cell means a cell that operates at a primary frequency and means a cell in which the UE performs an initial connection establishment procedure or a connection reestablishment procedure with the base station or a cell indicated by the primary cell during a handover procedure. The secondary cell means a cell that operates at a secondary frequency and once an RRC connection is established, the secondary cell is configured and is used to provide an additional radio resource.

The carrier aggregation system may be divided into a continuous carrier aggregation system in which aggregated carriers are contiguous and a non-contiguous carrier aggregation system in which the aggregated carriers are separated from each other. Hereinafter, when the contiguous and non-contiguous carrier systems are just called the carrier aggregation system, it should be construed that the carrier aggregation system includes both a case in which the component carriers are contiguous and a case in which the component carriers are non-contiguous. The number of component carriers aggregated between the downlink and the uplink may be differently set. A case in which the number of downlink CCs and the number of uplink CCs are the same as each other is referred to as symmetric aggregation and a case in which the number of downlink CCs and the number of uplink CCs are different from each other is referred to as asymmetric aggregation.

Meanwhile, the carrier aggregation (CA) technologies, as described above, may be generally separated into an inter-band CA technology and an intra-band CA technology. The inter-band CA is a method that aggregates and uses CCs that are present in different bands from each other, and the intra-band CA is a method that aggregates and uses CCs in the same frequency band. Further, CA technologies are more specifically split into intra-band contiguous CA, intra-band non-contiguous CA, and inter-band non-contiguous CA.

FIG. 7A Illustrates Intra-Band Contiguous CA, and FIG. 7B Illustrates Intra-Band Non-Contiguous CA.

LTE-advanced adds various schemes including uplink MIMO and carrier aggregation in order to realize high-speed wireless transmission. The CA that is being discussed in LTE-advanced may be split into the intra-band contiguous CA shown in FIG. 7A and the intra-band non-contiguous CA shown in FIG. 7B.

FIG. 8A Illustrates a Combination of a Lower Band and a Higher Band for Inter-Band CA, and FIG. 8B Illustrates a Combination of Similar Frequency Bands for Inter-Band CA.

In other words, the inter-band carrier aggregation may be separated into inter-band CA between carriers of a low band and a high band having different RF characteristics of inter-band CA as shown in FIG. 8A and inter-band CA of similar frequencies that may use a common RF terminal per component carrier due to similar RF (radio frequency) characteristics as shown in FIG. 8B.

In this case, F_(UL) _(_) _(low) means the lowest frequency of an UL operating band. Furthermore, F_(UL) _(_) _(high) means the highest frequency of an UL operating band. Furthermore, F_(DL) _(_) _(low) means the lowest frequency of a DL operating band. Furthermore, F_(DL) _(_) _(high) means the highest frequency of a DL operating band.

FIG. 9 Shows a Relation Between a Channel Band MHz and a Resource Block (RB).

As may be seen with reference to FIG. 9, a transmission bandwidth smaller than a channel bandwidth BWChannel is set. The setting of the transmission bandwidth is performed by a plurality of resource blocks (RBs). Furthermore, the outskirt of a channel is the highest and lowest frequencies separated by the channel bandwidth.

Meanwhile, as described above, a 3GPP LTE system supports channel bandwidths of 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz and 20 MHz. A relation between such a channel bandwidth and a resource block is listed in the following table.

TABLE 4 Channel bandwidth BW_(Channel) [MHz] 1.4 3 5 10 15 20 Transmission bandwidth 6 15 25 50 75 100 configuration N_(RB)

Meanwhile, intra-band contiguous CA bandwidth classes and their corresponding guard bands are as shown in the following table.

TABLE 5 CA Aggregated Band- Transmission Maximum width Bandwidth number of Nominal Guard Class Configuration CCs Band BW_(GB) A N_(RB, agg) ≤ 100 1 a1 BW_(Channel(1)) -0.5Δf1 (NOTE2) B N_(RB, agg) ≤ 100 2 0.05 max(BW_(Channel(1),) BW_(Channel(2))) - 0.5Δf1 C 100 < N_(RB, agg) ≤ 200 2 0.05 max(BW_(Channel(1)), BW_(Channel(2))) - 0.5Δf1 D   200 < N_(RB, agg) ≤ [300] FFS 0.05 max(BW_(Channel(1)), BW_(Channel(2))) - 0.5Δf1 E [300] < N_(RB, agg) ≤ [400] FFS FFS F [400] < N_(RB, agg) ≤ [500] FFS FFS NOTE1: BW_(Channel(j), j) = 1, 2, 3 is the channel bandwidth of the E-UTRA component carriers defined in TS36.101 table 5.6-1, Δf1 represents subcarrier spacing of Δf when downlink, and Δf1 = 0 in downlink. (NOTE2): In case that the channel frequency bandwidth is 1.4 MHz, a1 = 0.16/1.4, and in the remainder frequency band, a1 = 0.05.

In the above table, the brackets [ ] represent that the value therebetween is not completely determined and may be varied. FFS stands for ‘For Further Study.’ N_(RB) _(_) _(agg) is the number of RBs aggregated in an aggregation channel band.

Meanwhile, up to now, for a case where a maximum of two downlink carriers are aggregated, maximum sensitivity degradation (MSD) and the like have been researched. However, a situation in which three of more downlink carriers and two uplink carriers are aggregated has not researched up to now. Therefore, hereinafter, the situation will be proposed.

<Aggregation of a Plurality of Downlink Carriers and Two Uplink Carriers>

Hereinafter, when the terminal aggregates a plurality of downlink carriers and aggregates two uplink carriers are aggregated and when the terminal transmits the uplink signal using a carrier aggregation of two uplink carriers, it is analyzed whether interference leaks to the downlink band of the terminal and thereafter, a solution for the leakage is presented.

FIG. 10 Illustrates a Situation where a Harmonic Component and Intermodulation Distortion (IMD) are Introduced into Downlink Band when Uplink Signal is Transmitted Using a Carrier Aggregation of Two Uplink Carriers.

As shown in FIG. 10, presented is a scheme for preventing receiving sensitivity from being decreased as the generated harmonics component and intermodulation distortion (IMD) component flow into the downlink band of the terminal when the terminal transmits the uplink signal through two uplink carriers. Moreover, since a receiving sensitivity level in the downlink band of the terminal may not be completely prevented from being decreased with cross isolation and coupling loss by the PCB even though the terminal appropriately solves the decrease in receiving sensitivity, a scheme for alleviating requirements which the terminal satisfies in the related art is presented.

<Disclosure of the Present Specification>

For the 3DL/2UL CA band combinations, the present specification provides an analysis about the impact to the 3rd own receiving band by the harmonics and IMD products from the dual uplink transmission. For 4DL/2UL CA and 5DL/2UL CA band combinations, the present specification provides an analysis about the impact to the 3rd and 4th or 3rd, 4th and 5th own receiving bands by the harmonics and IMD products from the dual uplink transmission.

The 2^(nd) harmonics from Band 8 and the 4^(th) & 5^(th) IMDs fall into the own Rx frequency of Band 3. Also the 4^(th) & 5^(th) IMDs fall into the own Rx frequency of Band 8. But these impacts already has covered in 2DL/2UL CA_3A-8A.

Hence, there was no harmonics/IMDs impact to the 3^(rd) own Rx frequency of Band 3.
